ONE-THIRD TO WIOKHAM B. SPEAR, OF SAME PLACE.

PROCESS OF PRODUCING ALLOYS FOR ANODES.

SPECIFICATION formingpart of Letters Application filed January 19, 1881. (N o specimens.)

To all whom it may concern Be it known that I, WILLIAM FEISHMUTH, of the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Process of Producing Alloys for Anodes, of which the following is a specification.

The object of my invention is to provide a material suitable for the formation of anodes for the use of electroplaters; and to this end my improvement. consists in the process of producing the same, as hereinafter set forth.

My improved alloy is prepared from the following ingredients in the followiugmanner and proportions, to wit: One (1) pound of nickel oxide,one-half (1}) pound of fine carbon, two (2) pounds of cryolite,and two (2) pounds of a mixture of chloride of potassium and chloride of sodium, in a dry state, are to be thoroughly mixed together and exposed in a crucible to a white heat for a period of at least two hours, after which the crucible is removed from the. furnace, and will be found to contain an alloy of nickel and aluminium in balls or pellets of a metallic silvery-white appearance. Those are then to be mixed with carbon and borax, constituting a flux, remelted bya white heat, and cast in iron ingots or sand molds to any size or form desired for anodes or plates. The anodes so formed are in condition for use by the electroplater, either with a solution of the double sulphate or chloride of ammonia and nickel or with the solution of alloy of 1 Patent no. 244,445, dated July 19, 1881. i

aluminium and nickel for which Letters Patent of the United States No. 223,210 were granted to myself and H. B. Van Tronk under date of December 30, 1879.

Articles plated from anodes of my improved alloy receive a more perfect and a heavier coating, and are susceptible of a finer polish and finish, than those treated with the use of the anodes heretofore employed; and, further, my alloy may also be formed into rolled sheets and castings for the manufacture of sundry useful and ornamental articles.

I do not claim any white metal other than aluminium as combined with nickel; neither do I claim any of the fluxes herein mentioned, as they are well known; neither do I claim the alloy with copper or any other metal. 1

I claim as my invention and desire to secure by Letters Patent- 4 The process of producing, an alloy of nickel and aluminium consisting in fusing the followin g-named substances in substantially the proportions specified, viz: of nickel oxide one (1) pound, of tine carbon one-half ponnd,of cryolite two (2) pounds, of a mixture of chloride of potassium and chloride of sodium two (2) pounds, and finally the alloy being mixed with a flux consisting of carbon and borax, as set forth.

WILLIAM FRISHMUTH.
